How to convert twips to atomic units of length
1 twip is equal to 333,326.6914 atomic units of length, and 1 a.u. of length is equal to 0.000003000059778 twips. To convert, multiply by the conversion factor:
atomic units of length = twips × 333,326.6914
atomic units of length = twips ÷ 0.000003000059778Example: convert 15 twip to a₀: 15 × 333,326.6914 = 4,999,900.371 a₀.

About the twip
A twip is one twentieth of a point, or 1/1440 of an inch (about 17.6 µm). It's used internally by Microsoft Word, RTF files and older Windows APIs.
